The main purpose of the Calvin Cycle is to produce glucose.

Here are the steps of how the Calvin Cycle works:

1. Carbon Fixation: The enzyme RuBisCO catalyzes the reaction between carbon dioxide and Ribulose-1,5-bisphosphate (RuBP), a 5-carbon sugar, to form a 6-carbon compound. This compound immediately splits into two molecules of 3-phosphoglycerate (3-PGA), a 3-carbon compound.

2. Reduction: ATP and NADPH from the light-dependent reactions are used to convert the 3-PGA into glyceraldehyde 3-phosphate (G3P), a 3-carbon sugar. This is the same sugar produced in glycolysis in the cytoplasm.

3. Release of One Molecule of G3P: For every three molecules of carbon dioxide that enter the cycle, the cycle forms a total of six molecules of G3P. One of these is released from the cycle and used to make glucose and other organic compounds.

4. Regeneration of RuBP: The remaining five molecules of G3P are used to regenerate three molecules of RuBP. This step requires ATP from the light-dependent reactions. The RuBP is then ready to react with more carbon dioxide.

These steps repeat multiple times to produce glucose.
